Longobarditidae
Longobarditidae is a family of ceratitd ammonoids known from the early Triassic, included in the Danubitaceae The Danubitoidea is a large and diverse superfamily in the order Ceratitida of the Ammonoidea that combines five families removed from the Ceratitaceae, Clydonitaceae, and Ptychitaceae. Taxonomy Superfamily Danubitoidea * Family Aplococeratidae .... Longobarditidae includes genera formerly placed in Hungaritidae by the American Treatise on Invertebrate Paleontology, Part L, 1957 as well as genera that have been described since. Taxonomy Longobarditidae includes 17 genera, 16 distributed among 4 subfamilies plus one unassigned. Six genera were named prior to the first publication of part L of the Treatise on Invertebrate Paleontology in 1957, the remaining 11 since. ''Arctohungerites'', ''Groenlandites'', ''Longobardites'', and ''Noetingites'' were previously included in the Hungeritidae, ''Czekanowskites'' in the Meekoceritidae, and ''Pearylandites'' in the Sibe ...

Hungaritidae
The Hungaritidae comprises a family of ceratitid ammonites described in the Treatise,(Arkell et al. 1957), as involute compressed, discoidal, with keeled or sharpened venter, smooth to weakly costate. Sutures ceratitid, usually with numerous elements. Hungaritids are Middle Triassic in age spanning a range from about 247 Ma to 235 Ma. By current assessment six genera are included. :'' Hungarites'', type genus :'' Gevanites'' :'' Iberites'' :'' Negebites'' :'' Paraceratitoides'' :'' Perrinoceras'' Arkell, et al. 1957, in Part L of the original treatise lists instead: ''Hungarites'', ''Noetlingites'', ''Longobardites'', ''Neodalmanites'', ''Groenlandites'', ''Perrinoceras'', ''Arctohungarites'', ''Dalmanites'', and ''Prohungarites''. Only two have remained, Hungarites and Perrinoceras. ''Longobardites'' has been removed as type genus for the Longobarditidae Longobarditidae is a family of ceratitd ammonoids known from the early Triassic, included in the Danubitaceae The ...

Early Triassic
The Early Triassic is the first of three epochs of the Triassic Period of the geologic timescale. It spans the time between Ma and Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic Series, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic Era. It is preceded by the Lopingian Epoch (late Permian, Paleozoic Era) and followed by the Middle Triassic Epoch. The Early Triassic is divided into the Induan and Olenekian ages. The Induan is subdivided into the Griesbachian and Dienerian subages and the Olenekian is subdivided into the Smithian and Spathian subages. The Lower Triassic series is coeval with the Scythian Stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of Buntsandstein, a lithostratigraphic unit of continental red beds. The Early Triassic and partly also the Middle Triassic span the in ...

Ceratitida Families
Ceratitida is an order that contains almost all ammonoid cephalopod genera from the Triassic as well as ancestral forms from the Upper Permian, the exception being the phylloceratids which gave rise to the great diversity of post Triassic ammonites. Ceratitids overwhelmingly produced planospirally coiled discoidal shells that may be evolute with inner whorls exposed or involute with only the outer whorl showing. In a few later forms the shell became subglobular, in others, trochoidal or uncoiled. Sutures are typically ceratitic, with smooth saddles and serrate or digitized lobes. In a few the sutures are goniatitic while in others they are ammonitic.
